Electric Field due to Two Thin Infinite Plane Parallel Sheets of Change…

Electric Field due to Two Thin Infinite Plane Parallel Sheets of Change – Consider two large, uniform charged parallel sheets A and B, having surface charge densities σA and σB, respectively.
At P, EP = -(EA + EB) = -1/2ε0A + σB)
At Q, EQ = (EA + EB) = 1/2ε0A – σB)
At R, [ER = (EA + EB) = 1/2ε0A + σB)]
